It’s been a tough winter, but regardless of the snow, brutal cold and a late start to spring, myrtle spurge is back.

Myrtle spurge is an introduced ornamental from the same family as other noxious weeds such as leafy spurge and cypress spurge. 

In Colorado, it is commonly found in landscape plantings and flower gardens. Mature plants grow to heights of 4 to 6 inches with clusters of small yellowish green flowers at the top of the plant.

Triangle-shaped leaves are bluish green in color. A key identification characteristic of this plant is a milky white latex sap that oozes from any part that is broken off.

Preventive measures include removing at least 4 inches of the root when pulling myrtle spurge. The weed has a taproot, so the more this can be pulled out, the more effective it will be at preventing re-growth. It is also effective to remove plants prior to seed set.

This A list noxious weed specie may look harmless, but be aware that it is quite poisonous should you find it. The white sap within the plant can cause skin rashes, blisters, swelling to eyes, nose or mouth should it make contact in any of those places.

Avoid a trip to the emergency room by taking the extra precaution of wearing gloves and long sleeves while handling it. Immediately wash your hands afterwards.
